Great presentation! Shows how much of advanced technologies are needed for a single component.

The component isn't a turbine blade - it's a nozzle guide vane!

[@rkan2]

The title is wrong but they did mention it in the video. Tbh - these guide vanes get about as hot as the turbine blades so the manufacturing process overall probablybisn't that much different. Of course I'd still like to see it!

[@m_a_t_t6098]

@@rkan2 I was an engineering intern at a plant that did the first few steps in the production of blades and vanes. We forged titanium and inconel rods up to the first machining step before we sold and shipped them out. It was an interesting process, and to see how something that sounds simple can quickly turn complex. For example how exactly does the metal flow in the die? If it folds over on itself it is problematic, not just because it can create voids in the part. Or did you think about the expansion, and therefore contraction after it cools back down? How does that influence the forging dies? Definitely was the most interesting job I've had.

I remember the days, when a lot of jet engine and rocket engine parts manufacturing processes were top secret under. Some of those key manufacturing steps are still protected as classified under Missile Technology Control Regime (MTCR) even for parts destined for the civilian aerospace industry. For this reason, I find videos like this a miracle of freedom of information.

[@jac1207]

Well, the overall production steps is kind of well-known at this point thanks to globalization. The trade secrets are the formulas, specific design of tools/procedures/etc, steps unique to each company, institutional knowledge, basically the small details making up the vague production steps in the video.

[@louisazraels7072]

It's interesting how "artisanal" it feels (despite the abundance of high tech tools) compared to high volume manufacturing such as car components, no wonder these engines cost so much.

[@connectorxp]

Many test and certifications add a lot to the final cost, plus the extra care to make an Aviation Grade component with all the CoC and Form1 to be acceptable.

[@connectorxp]

@Will Swift COC mean certificate of conformity and Form1 is an EASA or/and FAA document that certifies that the part is approved to be installed on an aircraft. It's illegal to install a part without CoC or Form1 and the aircraft becomes AOG due to loss of airworthiness.

[@Happy.Viewer]

We 🤔 should wonder why the cost of Industrial Foods and Beverages are so much because most of them are not healthy Foods!. But not Safran, GE, RR,...Jet Engines. 🤗🍎🍏Sure, these Jet Engines are reasonable costs for us to enjoy our Flights more safety, daily.🍹🍹🍹

[@TricksterJ97]

@Will Swift as you move up the performance curve to approach what is just possible, the options to design around the problems become more limited and the safety factors smaller, hence you must compensate with careful process control and inspections.

[@Nainara32]

Considering that the part is a single piece of metal (in a complex shape) I'm a little surprised that it requires so many steps to cast. No wonder additive manufacturing was generating so much hype some years ago.

[@TheGroovers71]

Great video. Whenever I'm a passenger in a plane, I think about a blade that self destructs and causes massive engine failure and explodes and we're all gonna die. Now I feel better.

[@timecode37]

I think it's time we acknowledge that China's capabilities are way above reverse engineering by now. The education in China has become a lot better over the past decades, and by now China is among the strongest countries in reporting new patents. Also because pretty much every company in a first world country is too greedy they just outsource everything, so it's Chinese engineers doing a lot of the work already.

[@nagaraju.s166]

All good but the part being manufactured are segments of Nozzle Guide Vanes (NGV) and not turbine blades as you mention in the video. NGV's are fixed parts and the blades slides behind this leading to rotation of disk and shaft.

@@moriarteaa4692 they already print rocket engines, and those have very complex small features. Besides, I'd be wary of predicting we can't do something eventually.

[@moriarteaa4692]

Well this isnt Rocket science but aviation

[@moriarteaa4692]

Im sorry you May be right, but I am not sure how to get the position tolerances needed with 3d printing. Maybe a hybrid solution with machining?

[@TheNefastor]

​@@moriarteaa4692 yes and no. I suspect you may used to FDM 3D printers which, really, are hobby toys. Industrial 3D printers can produce titanium alloy parts using lasers, it's a totally different class of machine with a totally different price range. Combined printing / machining already exists as well but it may not allow you to make the part we just saw. Hard to tell. DMG Mori has been making that kind of machine for some years now : kzbin.info/www/bejne/fKPCgaGbmt6CaZY you can print, machine, print again, etc... which means you can machine areas of a part that will be unreachable in the final part. My initial comment wasn't so much about technical possibility, but adoption and the certification of parts produced that way.

thank you. This was beautiful

[@carmelpule1]

Excellent video but I do not think that at 8:19 those blocking parts which operate at high temperature are attached by using a solder bead!

[@williamsteele]

Actually, it's called "brazing"... and is very common to close openings in the casting. This video uses some terminology that might be slightly simplified, but in essence, the "solder" is the brazing filler material, similar to the way a pipe fitter uses solder to braze water pipes together. You'll note that those parts are not on the hottest sections of the part, however.

[@carmelpule1]

@@williamsteele Thank you for replying, but as the video is entitled "The birth of a turbine blade" and often speaks of " turbines", where blades handle high flame temperatures, rather than blades on "compressors" where temperates still rise due to compression ratios, I thought that " the solder or even the brazing I know of", would be struggling to operate at those turbine temperatuires. I suppose the fusing brazing properties can be used on higher melting materials. Guess all materials can be brazed as you said. Apologies for picking up on the soldered part!

[@williamsteele]

@@carmelpule1 So let me clarify a little more... when I said they're not in the hottest part, I actually mean of the actual turbine blade itself... those brazings are done on the bottom side (where the coolant side is) so they're not in the direct flow of the combustion gasses. That means they don't see the highest temperatures. Also, the metals actually do not experience the high combustion temperatures due to the cooling system, which allows a coolant (compressed air) to flow out and along the surface of the blades, keeping the hot gasses from actually coming in to direct contact with the blade.

[@henry2008kim]

@@williamsteele But that filler doesn't look very metallic.. what kind of filler metal is liquid at room temperature?

[@carmelpule1]

@@williamsteele Thank you for replying. my brother and I made a few model jet engines and making the diffuser, the slowing down of air to keep a stable flame, the hot stator, and the turbine was not so easy, but they all worked for a few hours, as we did not have the right materials, nor did we cool the blades apart from feeding the bypass air to the hot stator. Seeing your video I just marveled at the method of producing what was shown, and I could imagine the responsibilities which you carry. Thank you for your assistance and all the best with your very interesting work. I am an old man now and did work on the installation of the first British Naval ship that had jet engines installed, HMS Exmouth and it had two Proteus and one Olympus jet engine.

[@BradBo1140]

The best KZbin videos Ive ever watched was three episodes on how the British built the Rolls Royce engine. What you never got to see was how they formed the high temperature fan blades. They use some kind of method that blows the blades up like a balloon. Totally a company secret. After that I got interested in how they make those crazy light, big headed golf drivers.
